Application October 28, 1944, Serial No. 560,839

My invention relates to fittings for closet bowls and more particularlyto the collars used in connectingv the base of the bowl to the wastepipe bend. 1

In installations of the above character, the securing bolts are appliedwith heads under the ange of the bend collar rising upwardly through thebowl base to receive cap nuts while the floor under the said flangeusually lacks sulicient friction for the head of the bolt to keep thelatter from turning as the cap nut is applied. Many times this does notoccur, and the bolt keeps on turning with the nut and'making the taskdifficut and slow.

It is therefore one object of the present invention to modify the collarin a manner to lock the bolt after it has been applied, so that it maynot turn as the nut is mounted and screwed down.

A further object of the invention is to modify the collar in a manner topermit the standard bolt to be used, so that no special provision needbe made or parts secured for that purpose.

Another object of the invention is to construct the collar along linesof extreme simplicity and without the addition of any parts* thereto forthe accomplishment of the present purpose.

An important object of the invention is to provide an improved collarwhose cost will only slightly exceed that of the conventional collar.

With the above objects in view and any others which may suggestthemselves from the description to follow, a better understanding of theinvention may be had by reference to the accompanying drawing, in which-Fig. 1 is a side elevation of a conventional closet bowl installation,showing its base connections in section;

Fig. 2 is a top plan view on an enlarged scale of the improved collar;

Figl 3 is a similar fragmental view on a further enlarged scale showingthe manner in which the attaching bolt is locked; and

Figs. 4 and 5 are, respectively, sections on the lines 4 4 and 5-5 ofFig. 3.

1 claim. (cl. 28s-34) Referring specifically to the drawing, the closetA s was previously mentioned, a slight amount 2 of clearance is usuallypresent in the iioor below the collar iiange I3 in order that theheadsfof the bolts may find room under the flange. The bolt underconsideration is indicated at I8, and its head I0 is in the nature of athin, elongated plate, preferably rounded at the ends as indicated at20. In the novel embodiment, I do not apply the head of the bolt beneaththe collar flange I3, but lower the bolt head directly into an openingvZI in the top face of the side flange. As indicated more clearly inFig. 3, the opening referred to is similar in form and somewhat largerthan the head I9 of' the bolt. Also, the opening is extended on oppositesides with a pair of lateral cavities 22 whose outer limits or sidewalls are sufciently spaced to permit the bolt to be turned crosswiseand with the end portions of its head I9 lodged in the cavities 22 asindicated by dotted lines in Fig. 3. As seen in this figure, theclockwise turning of the boltthat is, in the same direction as the capnut 23 applicable above would be turned-locates its head I9 crosswise ofthe opening 2I and in this position the end portions of the head aredesigned to meet end walls 24 of the cavities 22.

It will be evident from the above explanation that when the head of thebolt I8 has once assumed the position just described, it is locked bothfrom being raised out of the opening 2I as well as from turning anyfurther. Thus, when the cap nut 23 is applied and screwed down, the boltwill not turn beyond the position mentioned and remain still while thecap nut is being turned. Since the regular thickness of the collarangeI3 will be insuiiicient to accommodate the cavities 2l and leave enoughtop and bottom 4stock in the ange, the latter is thickened downwardly asindicated at 25 in the region of the cavities 22. Fig. 5 shows thisfeature more clearly, and the same will either find the necessaryclearance in the floor I 6 or require very little work to produce thesame.

It will be evident from the above description that I have improved thecloset bend collar in a manner toellminate the application of the boltor any other fastening means underneath the ange I3, that is, any placewhere it is diicult or not feasible to keep the head of the bolt fromturning. On the other hand, the bolt is now entirely within and abovethe collar flange, and its application is in the open by simply loweringthe bolt with its head in the opening 2| and giving the bolt aquarter-turn. to lock it as described. The closet bowl base may now belowered to receive the bolt and permit the application and quickfastening of the cap nut 23. An improvement is thus had which makes noalteration in the bolt, and only requires the collar to be cast with aspecial core, occasioning but a slight extra expense in its manufacturewhen this is done on a production basis. The collar therefore remains ina single piece, and no extra part is added to the installation for thepurpose of the present invention. The improvement thus makes theapplication of the bolt and itslfastening a simple and quick operation.

While I have described the invention along` specic lines, various minorchanges or renements may be made therein Without departing from itsprinciple, and I desire to consider such changes and refinements ascoming Within the scope and spirit of the appended clairrnwV` I claim: q
